Animal Summary

The zoo's collection of tree frogs live in an aquarium where they can be seen climbing the walls and sitting on the rocks and plants.  Visitors sometimes have to look hard to find them because they also like to hide under the leaves and bury themselves in the dirt.

  • They can change their color from grey to green depending on what they are sitting on.
  • They are the largest tree frog in Wisconsin.
  • They can climb and rest on vertical surfaces because of a mucous layer produced by toe pad cells.  The mucous creates a sticky bond with surfaces that can hold the frog's weight.


The grey tree frog is an amphibian of least concern.


They are threatened by habitat change due to human development and pollution.
